LOOSE-LEAF BOOK DEVICE.

- Specification of Letters Patent.

Patented Jan. 21,1908.

Application led August 19. 1907. Serial No. 389.322.

LAND, citizen of the United States, residing at Kansas Oity,.in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Loose Leaf Book Devices, of which the following is a specification.

y My invention relates toloose leaf book devices and more especially to that class` comprising a casing, a pair of bars within and rockingly mounted at their outer. edges on the casing and slidingly interlocked at their inner edgesfso that they shall rock in unison, and provided with hooks arranged in sets and adapted when the bars are rocked in one direction to be swung apart and when said I' bars are rocked in the other direction to come i the hooks in one or the other of the positions together at their'free ends and form rings,- and springs interposed between the inner or adjacent edges of the'bars and tending vto press them apart, so as to secure the bars with referred to, and vmy object is to reduce. a device of this character which wi ll operate eHiciently and lreliably and is of .s'irnple,-

strong, durable and .cheap construction.

With this object in view the invention consists in certain novel and' peculiar features of construction and organization as hereinafter described. and claimed; and in order that it may be fully understood reference 1s to be had i to the accompanying drawing, in whichzi Figure l, is a top plan view of a loose leaf book device embodying my invention, but

with the top plate of the casing omitted. Figa. 2, is a central vertical section taken on the line II-II of Fig. 1, with the top late yof the casing in place. Fig.`3,isavertica transverse section taken on the line-III-III of Fig, 2. .Fig 4, is a detail perspective'view of a part of one of the hookcarrying bars. 1

In the said drawing, 1 ind'cates a channeled bottom-plate of inverted-arch form in cross section.

2A indlcates a'chan-nel'ed top-plate of arch form in cross-section and adapted to be .snapped onto plate 1 andto form. in conjunction therewith the casing of the device,

the ltop plate being pro vided at suitable points with' openings 3. ,4 y

4 indicates a pairjpf parallel bars'having their outer edges rockingly mounted in the channels of the bottom-plate and equipped in any suitable. manner with opposltely l bowed hooks 5 extending up .through the slots 3 and provided with serrated free ends -6, the serrated endsof each set of hooks being adapted to interlock together as shown inFigs. 1 and 3 or to be spaced apart as shown by dotted lines, Fig. 3. The inner edges of the bars are adapted to be formed. with projecting tongues 7'of Substantially right-angle form in cross-section, the tongues 7 of each bar being spaced apart a distance slightly exceeding the width of a tongue. The bars arev of identical construction but are reversed with res ect to each other so that one tongue of eac bar. shall fit snugly in the space between the tongues of the other bar, with the tonguesof each bar underlying the inner edge of the other bar. By this arrangement the Aupward movement of the inner edges of the bars is limited by .the impingement ofthe tongues of each bar against the lower sidel of the companion bar and inde endent longitudinal Vmovement of the' bars is prevented by the disposition of one of thev tongues of one bar between those of the otherbar, itbeing understood of course in this connection,that the same eect can be accomplished by providing-one of the bars with a pair of tongues and :the lother with a single tongue between said pair'of tongues. This construction howeverv wouldfnecessitate the employment of separate dies whereas by providing each bar with a pair o f-tongues a ingle die can be employed to -produc'ejboth 4At opposite sides of the tongues 7 each ba stantially right-angle shaped ton ues Sand f [9', the. former depending and the atter pro.- jecting upwardly from the bars, with the'. 9'5l f Wire or equivalent spring rods 10', theyparts 10( being so roportioned that the s rings are under slio t tension when the hoo '-carrying bars are depressed or elevated below or above 'the'plane of their pivotal action, the ten# sion on the springsl increasing as the bars 10,3 approach such lane. By this arrangement.

'it isl obvious vt at the .Springs by outward pressure against the inner edges. of the bars or rather against the tongues 8 and 9 on the inner ledges of the bars, .willtend -to hold the 11e I9.0 1s provided with one or more sets of subbars yieldingly depressed or elevated at such edges and heneewill hold the serrated edges of the hooks together or a art as indicated in .Fi 8 by full and dotted .lines respectively.

Io o en the rings', the hooks are grasped above t e top `plate and pulled apart, this acp tion overcoming'the resistance of the. springs and causing the bars to ,rock upward tothe osition shown by -d6tted lines, oose e'the rings are -openy the'perforated leaves, not shown, arel slippedl non the `bars will operate in unison.

Infact-the entire power ma be applied on the ring From the aboveldescription it-willfbe ftp-1 arent that I have produced a loose leaf book evice embodying the features of advantageenumerated as desirable, and I wish it to be understood that I reservethe right 'to makel such changes as properly'fall within the spirit and scopeV of the appended claims.
